Miele WM3740 Technical Fault F169
I was cleaning out my washing machine - the detergent drawer and the filter, I ran some hot water through the the empty detergent drawer slot to help soften the dried powder. The water ran through the machine out of the slightly loosened filter as I had just placed it back but left it loose to flush the water out. Shortly after there was a water proofing error. After tilting the washing machine to ensure the water didn’t wash back into the machine the error went away, but changed to a “Technical ! fault F169”.
I can’t find this error code anywhere in a manual, but the guidance for technical faults is to switch off and on again at the mains. Unfortunately, I don’t know where the mains are as I rent and I’m not sure what the issue is or what I’m supposed to do.
If anyone could help I’d appreciate it. All parts (filter and drawer) are back in place and I’ve switched the machine off using the normal power button.

Miele WM3740 showing Technical fault F169 after water entered machine during cleaning
- The problem
- After flushing hot water through the detergent drawer area with the filter left slightly loose, the machine showed a waterproofing error. Tilting the machine cleared that message, but it then displayed “Technical ! fault F169”. The user could not find F169 in the manual.
- Likely cause
- The strongest suggestion in the discussion is that water may have run into the base of the machine and activated a float switch/leak detection system. This is supported by the waterproofing error clearing after the machine was tilted. The exact meaning of fault F169 was not confirmed in the thread.
- What fixed it
- Suggested action was to disconnect the washing machine, remove the back panel, and check whether there is still water in the base and whether the float switch, if fitted, moves freely and is not stuck. If that does not resolve it, the advice was to contact Miele. No confirmed repair for F169 was posted.
- Checks to try
- Waterproofing error appeared after water was flushed through the detergent drawer area with the filter left loose
- Tilting the machine made the waterproofing error disappear
- Suggested check for water remaining in the base
- Suggested check that the float switch, if fitted, moves up and down freely and is not stuck
Safety: Disconnect the appliance before removing any panel. Further diagnosis should be carried out by a suitably qualified appliance engineer.

Hello RosieAnna. It might be that there is a float switch built into the base of your washing machine to detect leaks and some of this water ran into the base of the washing machine. This would also tally with the fault disappearing when you tilted the washing machine.

Hi Andy, Yes that's what I thought for the water proofing error, which is the error that went away. But then the "Technical ! fault F169" error appeared and that's the error code that I can't find elsewhere.
Thank your for replying.
The only thing I can suggest is disconnecting the washing machine and taking off the back panel to check that there isn't still any water in the washing machine's base and that the float switch if fitted moves up and down freely, and hasn't stuck.
After that there is nothing I could suggest except contacting Miele as I do not have any error code like that myself.
